CHARLES F. WOODRUFF, OF NEWBERN, TENNESSEE.

Letters Patent No. 88,428, lated March 30, 1869.

IMPROVEMENT IN WATER-ELEVATORS.

The Schedule referred to in these Letters Patent and' making part of thesama.

To all whom it may concern:

Be it known that I, CHARLES F. WOODRUFF, of

Newbern, in the county of Dyer, and State of Tennessee, have invented anew and improved Water-Elevator; and I do hereby declare that thefollowing is a full, clear, and exact description. of the constructionandzoperation ofthe same, reference being had to the accompanyingdrawings, making a part of this specification, in which- Figure l is anend View of the cylinder.

Figure 2 is a side view of the same, a portion being shown in section.

This invention is an improvement upon the devices patented by the sameinventor, February 4 and September 15, 1868, and consists in acombination, in one machine, oi' the main features covered by said twopatents, thereby producing a more simple and permanent, and lessexpensive waterelevator than either of the old ones.

In the drawings- A represents the cylinder, which maybe of Wood, or anyother material, and may be of any length desired.

To one endiof this cylinder is attached, by screws, or otherwise,'acircular metallic plate, B, having, at its centre, a journal, b, uponwhich the cylinder is supported at that end.

At the other end, and attached in a similar manner, is a circularratchet-plate, C, provided with four (more or less) holes, c c, and a`journal, c', the latter being made tubular, and supporting that end ofthecylinder.

' In the end ofthe cylinder, inside of the plate C, is a largecylindrical chamber, D, and at the end of that, a smaller chamber, (l,the axis of both being in line with that of the journals b c. I

In connection with the parts above described, I em-v within chamber D,two (more or less) arms, G G, branch outward, and then bend back'horizontally toward plate C, in such a manner, that when the shaft isrotated by the crank, the ends of the arms will come in line with theholes c c, and, if the shaft be not pressed inward by-hand, said armswill, by the pressure of spring s, be caused to enter the holes, andthereby engage shaft F and plate C firmly together, so that, if theshaft be further rotated, the plate and cylinder must rotate with it. Bypressing the shaft inward, it is disengaged again, and the cylinder isfree to rotate independently of it.

In drawing water with this simple device, it is only necessary to turnthe crank. rlhe arms will at once engage, and, by the rotation of thecylinder, the bucket will be elevated. u

When the bucket is emptied, the pawlmaybe thrown out ofthe ratchet, andthe shaft pressed inward. Y'.lhe bucket will, then, by its own weight,unwind the rope, and descend into the well.

It will be observed, that, besides the extreme simplicity of thisapparatus, which renders it more durable and less expensive than the oldones, the nature of it is such, that with the same set of castings, acylinder of any required length and size may be employed, and that,having the castings, anybody possessing the least mechanical skill canconstruct the whole device, and pnt it into operation.

I do" not claim any of the parts herein described, separatelyconsidered. Neither do I claim in this application anything shown ineither of my patents of February 4 and September 15, 1868; but, havingthus described my invention,

Vhat I claim as new, and desire to secure by Letters Fatent, is-

The combination of the plate 1B, having the journals b, theratchet-plate C, having the holes c c, and the hollow journal c', thechambered cylinder A', the spring s, the crank E, and the .sliding shaftF, having the arms Gr G, bent as described, the whole being constructedand arranged to operate together substantially in the manner and for thepurpose specified.
